22 Claims.

This invention relates to the preparation of laminated products, andmoreparticularly those in which a layer of. special surfacing materialmay be included, so asto obtain a surface hav- 5 ing a special .finishon one side or having ,re-

sistance against particular material with which it may contact. As afurther refinement also, such composite sheet material may be formedinto structures of tubular character to present a desired facingmaterial internally or externally. Other objects and advantages willappear as the description proceeds.

To theaccomplishment of the foregoing andrelated ends, the invention,then, comprises the features hereinafter fully' described, andparticularly pointed out in the claims, the following description andthe annexed drawings set-.

ting forth in detail certain illustrative embodi-. ments of theinvention, these being indicative 20 however, of but a few of thevariousways in which the principle of the invention may be employed.

In said annexed drawings: Fig. 1 is a diagrammatic plan view illustrat-25 ing the assemblage of a plurality of layers of taken'on aplanesubstantially indicated by line 5V, Fig. 2; .Fig. 6 is a diagrammaticplan view showing the feed movements between the severing means a'ndthemandrel; Fig. '7 is an enlarged detail on a plane substantiallyindicated- -at line VlI, Fig. 2; and Fig. 8 is an end view thereof. Inaccordance with'the invention, sheet material is laminated together, aspecial facing layer as desired being assembled with abody layer, andfor illustration a web of cellulosic material 45 as supplied from a roll2, Fig. 1, has an adhesive applied to one surface and is brought intoassembly with another web of cellulosic material from a roll 3, theassembled sheets forming a composite, which is then further handled inaccordance with the invention. Depending upon may be obtained in thefurther assembly; and

the composite as formed from the webs from rolls 2'and 3 in gluedtogether relation may be considered as traveling in the direction of thearrow 41, Fig. 1, the composite being then for instance severed intotransverse strips 4 which 5 will have the peculiarity of two layers atone end, the under layer as viewed in Fig. 1, being the specialsurfacing material, which extendsfrom the edge in to the dotted line 5,while the remainder .of the sheet I is of the general body 10 material.As readily seen, various effects may be had, depending upon theparticular materials introduced by rolls 2 and 3 respectively. As anillustration, the roll 3 may be of cellulosic material particularlyresistant to oils and greases, and the roll 2 may be of cellulosicmaterial of lower grade paper stock suitable for body usage. Thus, theroll 3 may be of oil-proofed paper, hydrated cellulose, parchmentizedpaper etc., and the roll 2 may be of 'kraft, chipboard, chestnut boardor other relatively cheap paper stock. By employing a water-proofmaterial as the stock roll 2,

a water-proof faced composite material may equally well be assembled, asreadily seen. And by one roll of facing material on one side havingoil-proof properties, and another roll in application for the other sidehaving -water-proof properties for instance, a composite ofcorresponding respective surfaces may be had. And, byadvancing thesheets 4 for instance in the dimotion of the arrow b to a furtherlaminating means bringing thematerial together in'the form of a wound-uptube, the latter may correspondingly have a-special facing inside orcut,-or both,

as may be desired. The mechanism 'efiecting these functions may vary inits detail, but one desirable form is illustrated, in which, as seen inF g. 3,'the roll'of paper 3 is placed in a suitable framing from whichit is fed forwardly, while a roll '2, suitably supported in the framingat a 40 point in advance of the roll 3, is fed to contact one surfacewith a gluing roller 1 and is then brought together into assembly withthe web from roll 3; This portion of the mechanism may involve adhesiveapplying means including an adhesive supply-pan 8 of suitable characterin association with the gluing roller 1, and the web of paper 9proceeding from the roll 2 passes over such gluing roller and receivesan application of the adhesive therefrom, and thence is diverted byguide rollers Ill, II, also passing a doctor scraper 8a, into assemblywith the web l2 from the roll 3. Beyond the point of assembly, anadhesive applicator is arranged to apply adhesive across the exposedface of the composite traveling thereunder, and such applicator maycomprise a glue-supplying roller .15 arranged to pick up the adhesivefrom a suitable pan IS in association therewith, and then feed theadhesive by means of distributing rollers l1, It, to the paper travelingthereunder. By mounting the rollers l5, l1, l8, in a pair of arms I 9which may be pivotally mounted at in a pair of brackets 2|,the rollersmay be rocked away from the paper. Such movement may be effected by link22 and lever 23 and any suitable operating means therefor, such as a camon shaft 26 to give the small movement required. Conveniently ahold-down arm 230. may also be operated by lever 23 through a link 23b,and thereby the paper is prevented from slipping when a cutter operatesupon it. The rollers l5, l1, 18, may be driven through suitable gearingfrom a sprocket chain receiving its drive in turn from the shaft 26.

Beyond the gluing means" is a cutter, which may be in the form of aknife or rather a pair of knives 30, 30a, Fig. 3a, extending across thewidth of the composite sheet material and being workable shear-wise bysuitable means, as for instance a rack 3|, Figs. 3, 3a, operated by alink 32 through the bell crank lever 34 fulcrumed on the frame at Ma andhaving its free arm operated by a cam 34b on shaft 26. The severingblades, urged apart by a spring 3Ia between projections on therespective blades,

may be moved together by cams 3lb on cross shafts carrying pinions 3lcoperated by the rack 3|, the cams being set appropriately. By cuttingthe composite sheet material into transverse strips of adapted width 9.suitable dimension thus may be had for further laminating in wind-upoperation to the formation of a tubular body. To carry the cut strip forthe further operations, a.gripper is provided which is movable to aposition adjacent and parallel to the severing knife, the gripper Gbeing suitably mounted to then move in primary path, asindicated in Fig.6 back to a position remote from the cutter and parallel, and then bemoved axially in a secondary-path tocarry the cut sheet into the jaws ofthe mandrelfeeder'F, which being in a position to receive the end of thecut sheet then moves forwardly to present it to the windup mandrel m,Fig. 2. Thus, as seen in Fig. 6, the gripper G in its dotted lineposition seizes the web and carries it back to the position at the leftof Fig. 6, in dotted line, and the knife means 30, etc., severs the web,then the gripper G moves axially to the full line position shown,whereby the end of the cut sheet is put into the feeder F in its fullline position shown, and thereupon the feeder F advances forward to thedotted line position, adjacent to the mandrel, to carry the, sheet tothe mandrel-gripper. The S ipper G, Figs. 2, 7 and 8, may involve amovable carriage assembly and comprise a lower jaw ii, an upper jaw 52movable relatively thereto in gripping and releasing action, andoperating mechanism; the latter being of detail as desired. Forinstance, spring means 53, Fig. 8, at the back beyond the pivot fulcrumof the upper jaw in lugs 54 may serve to close the upper jaw, while arack bar 55 movable axial-wise of the jaws and carrying inclined wedgesa which slide against coacting wedges on the back of the jaw 52 may beprovided to effect release. The jaw structure or gripper can slideaxial-wise in the guide carriage El and the carriage can slide bodily inframe guide 1. While the gripper carriage is mes es going through itstravel movement from the cutter 30 back and across to the mandrel-feederF and return for a new charge, undesirable prolonged action of the glueroller l8 on the paper is prevented by the roller being raised from thepaper bycam 34b, lever 23 and mounting l9, etc. At the same time, thelever raises the holddown 23a so that the paperis'feedably pulled alonginfeed-movement in timed cycle; and it will be observed that the end ofthe paper (the cutter 30 being now open), is in position to be seized bythe gripper G appropriately and be then pulled out thereby, whereuponthe cutter 30 operates again, and the gripper goes across with its cutstrip tothe mandrel-feeder F, thence to return to the end of the paperweb again for a repetition of the cycle. The movement of the grippercarriage G back and forth in the slide guides ,f is effected in timedrelation by suitable means, as for instance the carriage having a rack56, Figs. 2 and 3, operated by a pinion 51 whose shaft-is rotated' iormovement of: the carriage toward the cutter by sprocket 58 and unwindchain 59 pulled by a tension spring 60, while for reverse movement theshaft of the pinion 51 is turned by gear segment 6| which is fulcrumedat 62 on the frame and its extending arm has a cam follower 63 operatedby a suitable cam 64 on shaft 65. The carriage desirably has guide rods6 slidable in the frame. Movement'of the gripper axial-wise in thecarriage is effected by a suitable means, as lever arm 68 having itslower end pivoted and its upper end to be received between idler rollers81 projecting from the gripper, the leverv arm 68 part of the timeresting passive, the timing being such that the end 'of the lever arm 68is in a position to come between the idler rollers 61 when the gripperis moved from the cutter to its remote position. Reversely, the leverarm 68 is thrown back by thecam 69 and slides the gripper back to aposition away from the mandrel-feeder F, and the gripper carriage maythen be moved bodily back to the cutter in repetition of the cycle withthe lever-arm 68 in readiness for use. In detail further, for actuationof the movable jaw 52 of the gripper, while the jaw-closing spring 53has a constantly-acting tendency, the jaw-opening in timed relation maybe provided by movement of the rack 55 by means of pinion 14 carriedwith the upperjaw and having on its stub shaft a. crank IS in positionto be appropriately turned by tripper-arms I6, 11, these being mountedfor suillcient slide movement in slideway 18, Fig. 2, and thetripper-arms being connected to a slide rod 19 having operating lever13a on a short vertical shaft 19b whose lower end is provided with acam-arm 19c engaging cam 19d. With this, after the gripper presents itsout strip to the mandrel-feeder F, the tripper-arm It is pulled back bythe mechanism recited, it having been sufficiently advanced toward themandrel-feeder F to allow free transit of the gripper-crank l5, and thenin such movement in the direction away from the mandrel-feeder F the armI6 turns the crank I5 and the pinion I4 and thereby moves the jaw-rack55 to release jaw 52 of the gripper so that the mandrel-feeder F canmaintain the out strip. Further movement of the arm 16 shoves the crankI5 and the gripper with it back to position remote from themandrel-feeder, ready for bodily movement of the gripper carriage G backto the cutter 33. After the gripper has received a new charge and isready to be returned back away from the cutter, the arm 'I'I comes intooperation and in its may set the gripper jaw and hold the cut stripwhile the carriage is then moved away from the cutter, the cutter beingopen. Continuing movement of the arm 11 now shoves the crank 15 andgrippermechanism in its carriage G forward to position adjacent themandreLfe'eder 'Reof the carriage away from thef mandrelv feeder iseifected by the cam 69 operating the and s 'gle layer thickness at theother edge, is'advancedfunderthe adhesive applicator l6, l1,

lever 66 through the cam-lever I0 and compensating link I l. The feederF may involve a pair of fingers 35, 36, Fig. 5, the latter beingopenable relative to the former, and both being carriedby suitablebracket. means 3T on slide. rodsl36, whereby in retracted position ofthe finger-carr I ryingbracketmeans- 31, the fingers may. receive f.length,l,th eir, length in this case being transverse of theoriginally-directed travel of the sheet material, such .dimension, asindicated,, being parthe cut sheet, and carry it forwardlyto the windupmandrel m. The reciprocating movement of the feed fingers may beprovided by suitable drive means, such as a lever 39 which may beoperated in turn through a slot-wise connection by a link ,46 which isreciprccated by a camll operating on cam-followers 42, 43, on the link.The movable feed finger 36 is opened and closed in timed relation withthe movement of the slide, such asto be open at the moment of being inposition to receive the end of the cut sheet, that the latter may rideinto the opening between the fingers, but on the starting of the returnmovement of the slide the finger 36 is pressed against the sheet, andfrom its shape and relative weight, frictionally engages the sheetduring the moving in the feed-direction, toward the left as illustratedin Fig.5. Operating means for this may be for instance a pressure arm36a bearing upon other arm 36b extending angularly, pressure maynormally be'applied to the feed finger 36, but on periodic engagement ofthe arm 361 by a release lever 360 the holding pressure on the feedfinger 36 may be momentarily released to allow feed of a fresh sheetinappropriate timed relation. with the lever 36c fulcrumed at 36d, itsmovement may be controlled by a link 44, pulled down by cam operatingagainst cam-follower 46 on the link, while the. reverse or raisingmovement Y may be accomplished by tension spring 41 extending from thelink 44 to, a fixecl point, on the framing. If-the feed finger 36 be apair of feed' fingers arranged side by side, as shown in Fig. 2,

two strips as split by a s l'itter i49-maybe fed to .the mandrel msimultaneously and two tubes may be wound up atthe same time, instead ofone, if preferred- Arrived at the wind-up mandrel m, the timing issuchthat the latterpresents open gripping means ready to seize the advanceend of the sheet. Such gripping means may comprise gripper elementshaving intermeshinggearteeth, and driven through intermediary gearelements from anaxially-extending"internal stem which at its outer endreceives'interrnittentmotion oscillatingly 'at appropriate timedintervals to open and close the gripper elements.- An advantageousconstruction is set fortl'r'in' detail in' my copendingapplicationSeruNo. l60,029,..filed August In 'the operation of making upa laminated ticularly detailed here.

the assembled material .now inthe stage of .two ,layer thickness atoneedge,.as,seen in Fig. 1,

l8, and elves a coating of adhesive on the a e opposite from the specialsurface ence proceeding to the cutter 30, the

po e heet material is cut into strips, which are relatively.narrow' ascompared with their ticul'arly; suitable for feed to a tubular winding-.iip mandrel, and to this end,the cut strip is carried by the grippercarriage G to the feed fingers 35, 36, which'then carry it into the"gripper jaw of the mandrel m suitably positioned at thatmoment, and thelatter in its rotation winds the strip over and upon itself, the specialfacing layer being internally against the mandrel surface, while theadhesive-coated surface is' on the outside and thereby the successivelayers as laid on are joined v together into 'a" laminated tubularstructure. Further compacting may be had if desired by a pressure rollerwhich may be springtensioned against the mandrel and material thereon.At thevcompletion of the winding operation, a slide-collar 80 pushes thewoundtubular body axially along the mandrel one step, in order to clearthe mandrel for the next oncoming strip to be wound. .The collar 80 maybe reciprocatively moved by any suitable means, for

instance a cam and lever and link connections to a slide carrying thecollar, as need not be par- If desired, the tubular body may be furthersurface-finished exteriorly by application of a cover layer, or thesurface may be treated by liquid, or both, in accordance withparticularly-desired character and intended usages.

As a'further refinement, in assembling the sheet material from thestock-roll 3',with that from the stock-roll 2, it is advantageous insome instances to so relate the respective layers that a specialsurfacing layer fromthe roll 2 slightly extends beyond the margin of thesheet material from roll 2, as indicated in dotted line at the loweredge of Fig. 1. Then, in being directed into assembly with the web I2,such projection in the margin is turned up and over in traveling againsta suitable guide 86, Fig. 3,"and is flattened into place by ninningundersmoother i and is pasted down, covering and guarding the winding-upstarts on the mandrel, is such-"that there is no possible exposure ofthe poorer body 'stock'la'yer, but-only-thespecial liner material is inexposure, and thereby when used as' a-con-' tainer, withsuitable-closure heads, liquid contents as for" instance oils, maybe-excluded from working into the backing layers by any possibleexposure of, unprotected material, 'even" in "very slight extent, at theseam.
